Hi Everyone!

I have been a lurking member for a while.

I just pulled the code for my check engine light this morning. I bought a V-Checker off Ebay and it arrived last night. I received the same code P2098 "Post Catalyst Fuel Trim System Too Lean". I set the device to Professor mode and then set it to Benz.

Osofast2 - I live in Lexington as well. The signal came on twice in the last month. It disappeared the first time. The second time it came on after I filled up with premium gas after a tankfull of regular my wife accidently pumped a few days before. I think its the gas, but I don't know what to replace or rest.
